After the replacement the engine temperature climbs to 87C just after 2 miles, which is supposed to be, right? It remains at 87C all the time except for stop-and-go traffic, which is about 90-95C.
Someone pointed out to me that the old thermostat was definitely bad, it appears in the picture open, so I'm adding another pic to see it more clearly. The gasket sat very tightly, I had to pry it out with a hook, it looks a bit torn.

You should be able to watch the thermostat open if you place it in a saucepan of water and heat it up on your stove. If you also have a thermometer, you can note the precise temperature when it moves.

The bad one stays open all the time, and the new one is already installed. Next time then, thanks! :-)
you are perfect now on a 60f day in the big D.Now get the techron or seafoam in and see if you can get those mpg's up.
Thanks ohlord, I'm gonna take the measurements one after another, to see which one really kicks in. If I did them all at the same time I would not know.
And based on the fact that your old one was stuck open, I'd bet you'll see a decent mileage improvement. Particularly if you're in a colder climate, then engine would take a long, long time to get to operating temperature, and if you were driving moderate roadway to low freeway speeds it would probably never really get to the proper temp. Surprised this didn't reflect on the dash gauge.
Take care and enjoy the ride,
Greg

It did, as I said I got just about 70C even after 20, 15 miles driving, the whole time before the replacement.
I have an 2002 Acura MDX, it is notorious for its transmission. It had a recall on the transmission and Acura had to add a "fluid jet" to cool some internal part down. My MDX's transmission was declared "transmission failure" by Acura dealership and it was replaced under warranty. (There were many MDX owners had their transmissions replaced under warranty.)
After the transmission was replaced, a side effect was that I gained 1 mpg (according to the built-in computer), from 15.8 mpg to 16.8 mpg (city and freeway combined).
I'm not suggesting that you have a transmission problem for your not-so-good mpg on your MB; certainly not recommending you to replace your transmission. I only thought that it's interesting to mention it.
